The magnitude of children's exposure to ambient O3 and PM2.5 and the inter-individual variability in children's exposure were studied. The magnitude and variability in children's exposure were closely associated with children's daily time patterns, varying among individuals by a factor of 7 and 11 over a 95% frequency range for PM2.5 and O3, respectively. The four most important microenvironments to children's daily exposure were home, school, outdoor, and vehicle microenvironments. High end PM2.5 exposures to school age children in Hong Kong were quite high for the October 2011 case study relative to levels that may be of health concern. The estimated high end O3 exposure concentrations were not particularly high. This is an abstract of a paper presented at the 108th AWMA Annual Conference and Exhibition (Raleigh, NC 6/22-25/2015).
